1 Claim.

This invention relates to supports. More specifically, it is concernedwith rack-like structures designed for the support of shelving, ing orany other elongate objects.

The chief aim of our invention is to provide a rack structure suitablefor the stated purpose of which the component parts interlock one withanother, without necessitating the aid of any separate or specialsecuring means, in such a manher as to be easily and quickly assembledor disassembled, and capable, moreover, of being set up to support oneor more shelves at selectively different elevations.

Another object of our invention is to secure the aforementionedadvantages in a supporting structure whereof the component parts lendthemselves to expeditious manufacture in quantity from inexpensivematerials at small cost.

Other objects and attendant advantages will appear from the followingdetailed description of the attached drawings, wherein Fig. l is a view,in side elevation, of a supporting structure conveniently embodying ourinvention.

Fig. 2 is a fragmentary perspective view of the structure drawn to alarger scale.

Figs. 3, 4 and 5 are detail sectional views taken as indicatedrespectively by the arrows III-III, IVIV, and V-V in Figs. 1 and 2; and

Fig. 6 is a fragmentary view illustrating the procedure followed inassembling the parts.

As herein exemplified, our improved supporting structure comprises anupright component ID, a horizontal bracket component II, and a bracecomponent I2, all cut from rolled channel section bar stock which may beof metal or any other suitably stiii and rigid material. The upright andracket components I0 and II are straight, and the brace component I2 isupturned at an obtuse angle at one end as at I3. In the region of thecurved bend in the brace component I2, a rib I4 is pressed out of themain or cross web of said component for stiffening purposes. Formed inthe main or cross web of the upright component It is alongitudinally-extending series of equallyspaced rectangular aperturesI5. The ponent i2 is provided with a single aperture I6 of the same sizeand configuration in its upturned or distal end portion I3. At oppositeends the bracket component I! has key formations I7 and 58 which are Tshaped and constituted by extensions of its main or cross web. A similarkey projection I9 is formed as a prolongation of the main or cross webof the brace component I 2 at the end opposite the upturned end portionl3 thereof.

cables, pipbrace com- 2 The key ends I! and IQ of the bracket and bracecomponents I I and I2 are adapted to detachably look into adjacentapertures I5 in the upright component [0, and the key end I8 of saidbracket component to similarly lock into the aperture IS in said bracecomponent as shown in Figs. 2 and 4. In order to make possible the readyassembling of these parts, the necks of the key projections are madeslightly less in width than the width of the apertures, and the width ofthe T heads slightly less than the diagonal dimensions of the apertures.

In assembling, the bracket component II is tilted at an angle about itslongitudinal axis and its key end I! introduced into one of theapertures I5 in the upright component I!) as shown in Fig. 6, and saidbracket is then turned so that the side notches of the T head engage andlock with the side edges of said aperture. A similar procedure isfollowed in engaging the distal key end it of bracket component I I intothe aperture It in the upturned end [3 of brace component I2, and inengaging the key end IQ of said brace component into the aperture IS inthe upright component l0 next below that occupied by the key end I! ofsaid bracket component. The three parts are thus easily and quicklyassembled and are thereafter held against relative displacement withoutthe need for any separate or additional securing means. Disassembling islikewise easily and quickly accomplished, and due to the provision ofthe many serially arranged apertures I5 in upright component IE3, thebracket and brace components II and I2 can be connected to said uprightcomponent at any desired elevation.

In practice, several assemblages such as above described are used inlaterally spaced relation to form, as exemplified in Fig. 1, a racksuitable for the support of a shelf 20 on the braced bracket componentsII, the upright components I0 being bolted or otherwise fastened to awall W or any other vertical surface or surfaces. It is to beparticularly noted that the upwardly-projecting ends I3 of the bracecomponents l2 serve as stops to retain the shelf 20 on the bracketcomponents II of the series. If desired the shelf 20 may be fixed inposition by means of bolts (not shown) for the passage of which thebracket components I! are provided with slots 2| in their cross webs.Obviously, several bracket and brace couples may be employed inconnection with each upright for the support of as manyshelves atdifferent elevations.

The supporting structure of our invention can,

cross web; a straight of course, be employed in many other ways and forother purposes than herein illustrated by way of example as will bereadily apparent.

Having thus described our invention, we claim:

As a new product of manufacture, a supporting structure of the characterdescribed comprising an upright channel section bar adapted to beaffixed to a wall and having rectangular apertures at intervalslengthwise thereof in its integral T shaped key its cross web releasablybracket bar having an formation at one end of horizontal channel sectionlocked in one of the apertures in the upright bar; and an angularchannel section brace bar having an integral T shaped key formation atone end of its cross web releasably'locked in another aperture in theupright bar and having an up-turned distal end portion provided in itscross web with a. rectangular aperture for releasable locking engagementwith an integral T shaped key formation at the distal end of the crossweb of the bracket bar.
